'He just hasn't won a major, but he's playing pretty good and he's going to be back,' Watson said Tuesday on 'CBS This Morning.' 'He's definitely going to win again.'

Woods, 36, has insisted he has at least a decade to add the four majors to catch Nicklaus, who won his last major at age 46 in the 1986 Masters. Watson agrees with Woods' view.

'You know, if he stays healthy, I think for sure,' he said, 'because he's still got 10 years to get to where Jack was. So, he's got 10 years to produce four more victories.'

Woods has two PGA Tour wins this season, at the Arnold Palmer Invitational in March and the Memorial Tournament earlier this month, but has failed to capitalize on the momentum from both in ensuing majors. He shot 8 over on the weekend at the U.S. Open to go from a tie for first to a T-21 finish. At The Masters in April, Woods finished in a tie for 40th place.
